requirements (Falk et al. 1999). However, there is a question as to whether 100% manual deconstruction of military barracks will yield optimum economic and environmental savings, particularly for those barracks built before World War II. The possibility of recovering timber and lumber from buildings is dependent on both physical and economic factors, which include: * wood condition, dimensions, and species * type and number of fasteners per piece * exposure or protection from the elements * labor cost * allowable building disposal period * site configuration and building height * allowable on site recovered materials storage time The demand for nonvirgin timber and lumber can increase due to the following: * Harvesting restrictions on high-quality, large-diameter, old-growth timber restrict its availability at any price. * Prices of forest products are steadily increasing. * Exposed timber frame construction demands high-quality large timber. * Older species-specific wood may be desired for use in new log home construction and interior remodeling of older buildings. * North American species may be considered "exotic" creating a demand in those markets. * The more nonvirgin timber and lumber is used the more familiar buyers, designers, and builders will become with it.
